Bitranked Podcast

Paying a friend back two dollars in bitcoin sounds simple, but on the main Bitcoin blockchain, a wait of up to an hour and fees that can eat a big chunk of it make small payments impractical. In this episode of the Bitranked Podcast from bitranked.com, Ryan and Daniel break down why Bitcoin handles transactions this way, and how the Lightning Network solves the problem by making micropayments near-instant and nearly free.

In this episode:

• Why Bitcoin payments wait in line, and why fees rise when the network is busy
• How payment channels let two people pay each other again and again, with only two entries on the blockchain
• What stops someone from cheating, and why somebody has to keep watch
• How a payment hops through other people's channels without anyone in the middle being able to keep it
• What you need to get started: a Lightning wallet, sats, and the choice between custodial and self-custody
• Where Lightning falls short: receiving limits, staying online, and large amounts
